A method for signal strength detection begins by comparing a signal
strength representation of a signal with a signal strength representation
of a reference signal. The method continues by adjusting, when the signal
strength representation of the signal compares unfavorably with the
signal strength representation of the reference signal, at least one of
the signal strength representation of the signal and the signal strength
representation of the reference signal until the signal strength
representation of the signal compares favorably with the signal strength
representation of the reference signal. The method continues by
determining signal strength of the signal based on the adjusting of the
signal strength representation of the signal and signal strength of the
reference signal.
